To all whom it'may concern:

Bait known that we, Premiers A. Dus- LAURIERS and Louis P. Dnsmonrnus; citizens of the United States, residing at St. Paul,

in the county of Ramsey and State of lldinnesotm have invented certain-new and useful Improvements in- Column-Molds, of which the following is a specification.

' Our invention relates to improvements in means for constructing concrete columns and particularly consists inproviding means for so supportingthe mold. for forming the top of the column'that it may be easily taken down without interfering with the supportin}: frame work for the ceiling mold.

. To this end our invention consists in the features of construction, combination and arrangement of parts hereinafter particularly d'escribed and claimed.

In the accompanying drawings forming 'part of this specification, Figure 1 is a perspective view of our features of invention arranged in connection with a column mold and ceiling mold; Fig. 2 1s a side elevation of the top of the column mold in connection with a ceilingbeam mold; Fig. 3 is adetail;

pfa securing block forming part of our iniventio n; Fig. l is a top view or the features shown in Fig. 2'; Fig. 5-is a detail of a plate forming part of thecolumn top mold; and Fig. 6 is a detail view of removable supporting means for-the top of the column mold. j

' In the drawingsthe column mold-is shown composed oftelescoping sections-2, the top section 3 being shaped to form'the cap of a outwardly extending flange 21 forming in 4 use a support for the adjacent'ceiling mold 'openingYS in the frame work 6 to receive the column top with bracketsfi supported in the corners of the openmgs. To support the colunm top from these brackets we provide a plurality cf clamps each consisting of a flange :21.

jaw 10 to bear against the outer face of one of the brackets and jiaw l1 slidable through an opening 12 in the lower end of'-the .jaw 10. The jaw 11 is adapted to bear against the inner face of the block 3 andto hold the same against the inner face of the framework, the block 13 forming a rest for the In the form of column shown, both jaws 10 and 11 are bent to extend away from the brackets and block and permit a tilting movement of the jaws. The opening 12 and the jaw 10, through which the arm of the jaw ll-passes, is inclined and is relatively larger than the arm'of the jaw 11 so that with the clamping jaws in the position shown in Fig. 6, the lower end of the jaw 10 being driven inward will grip the arm of the jaw 11 to hold said jaws in clamping position. To loosen the jaws it is simply necessary to drive the lower end of the jaw' 10 outward to release and separate the jaws; It will be apparent that with the blocks 13 and clamps in position and the column top. resting upon the blocks, the column top will be firmly supported in connection with the remainder of the-column and ceiling mold, and by loosening the clamps the column top may be taken out of the opening without interfering with any of the ceiling mold plates.

In Figs. 2 t6 5 we show means for conmeeting the top section of the column mold with a beam mold 14L. In this adaptation the top column section will be constructed to form vone side of the column top and has adjust-ably secured to its inner edge a band 20 formed with a flange 15 to aline with the adjacent side wall of. the beam mold. Blocks 16 are secured as'by means of screws 17 to the adjacent side of the beam mold and are each formed with. an inwardly extending flange 18 to bear against the flange 15 of the plates 20. In this adaptation as in the full top shown in Fig. l, the top flange 21 is adapted to be supported by blocks corresponding to the blocks 13. The bottom of the top alongside the main columusection may be secured tothe bottom of the beam mold as by means of adjustable connecting tplates 22. In. use, in order to outwardly adjust the position of the main column mold with reference to the beam the plates 20 and 22 will be adjusted withreference to the mold support may e shown it will be evident that the column mold may be set up in connection with the ceiling molds but may be easily and quickly taken down without interfering in.any way with the ceiling molds.

The particular means for supporting the column top in connection with the ceiling varied without departing from the idea of our invention, the scope of. which is defined in the claims.

We claim as our invention:

1. Means for forming a unitary column and ceiling comprising movable ceiling molding means formed with an opening, a supporting framework therefor formed with an openingalining with said ceiling mold opening, a mold for the top of the column arranged within said framework opening, an outwardly bent'flange carried by the upper edge of said column top mold, and

blocks removably carried by said ceiling mold supporting framework inside said framework opening in position to extend underneath and form a support for said flange.

2. Means for forming a concrete ceiling and connected column cdmprisins; in combination a sheet metal mold for forming the 'top of the column, an outwardly projecting flange carried by the upper edge of said mold, a sheet metal mold plate for said ceiling, a supporting frame-work for said mold plate, blocks fitting underneath said flange to support said column top mold, and clamps removably supporting said blocks from said frame work.

In testimony whereof we aiiix our signatures in presence of two witnesses.
